TYPEWRITING-MACHINE.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application led Aug-*ust 12, 1919. Serial N0. 316,981.

To all whom it may concern Be it'known that I, JOHN WALDHErM, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting- Machines, of which the following is a specifcation. l

Thisinvention relates to typewriting machines to be used for writing upon a number of superposed sheets, especially webs. or continuous sheets from which typed sections are intended to be torn off. Such webs are often made in the form of fan-fold webs comprising a series of printed forms, each length of form adapted to be severed and removed when the typewriting thereon is com leted. In such work it is desirable to emp oy carbon-sheets or the like interleaved with the webs for making duplicate copies.

In the use of such carbon-sheets practical diiiiculties are encountered, especially in round-platen machines, in shifting the carbonsheets from the 'portions of the webs that have been ivritten upon, back to new positions for writing upon the succeeding portions of the webs. These difficulties are due partly to the fact that the webs have to pursue a tortuous course in passing through a round-platen machine, causing the carbons to be bound between the plies of web.

According to the resent invention, the webs need not be entirely straightened, but the amount of their curvature in passing around the platen may be reduced/to a comparatively'small arc so as to ease the webs at the time it is desired to shift the carbonsheets. This arc may be made small enough to enable the carbonsheets to slip readily between the work-sheets, without displacing the platen. To obtain these and other advantages, I have contrived to introduce the horizontal webs in a front-strike typewriting machine, substantially at the bottom of the platen, so that they curve forwardly -up to the printing point, and for writing purposes may emerge rearwardly and upwardly from the platen.

When it is desired to shift the carbonsheets relatively to the web, the web may be opened out or nearly straightened. To permit this to be done, in the form herein illustrated, a paper-table or directrix above the platen is adapted to be swung forward until the webs are cast off from the front of the platen and stand at an inclination upwardly and forwardly from a point somewhat below or near the printing point, thus reducing the curvature of the webs to an arc of some 40 to 60, this being suiiiciently small to release the carbon-sheets from the grip of the work-sheets and permit the carbons to be slid back to face fresh portions of the superposed webs.

To enable this swinging forward of the webs to beeasily accomplished, the papertable aforesaid may be journaled preferably upon the platen axle, and, while turning from its normal writing position, may automatically cast off the usual feed-rolls. The carbons may now be readily drawn rearwardly by any suitable device, such as the Underwood fan-fold machine carbon-paper carriage, one form of which is illustrated in the patent to Wernery & Smith, No.

1,132,055,0f March 16, 1915.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional side view of an Underwood standard typewriting machine modified to show one form ofv my invention as applied thereto.

Fig. 2 is a fragmentary perspective view of a carriage, showing the parts in writing position.

Fig. 3 is a fragmentary sectional side view of the carriage and a type-guide, showing the parts positioned for withdrawing the carbon-sheets.

In the Underwood typewriting machine, keys 1, when depressed, carry down keylevers 2, causing sub-levers 3 to swing typebars 4 upwardly and rearwardly against a platen 5, which is journaled by its axle 6 in a shift-frame 7. Every time a type-bar 4 approaches the platen, a heel 8 uppn it strikes a universal bar 9, to actuate the usual dogs 10 which control the carriagell by means of an escapement wheel 12; the connections. including a pinion 13 connected to the escapenent wheel and a. rack-bar 14 connected to the carriage. The shift-frame 7 is supported in the carriage partly by arms 15 connected by a shaft 15, and it also comprises a roll 16 running upohthe shift-rail 17. Normally, the lower-case types 18 print through a ribbon (not shown) at the typeguide 19 upon the platen 5. When, however, a shift-key 20 is depressed, an arm 21 fast to the shift-key swings upwardly the frame 22, which includes the shift-rail 17, so that upper-case types 23 print instead of the lower-case types.

The carriage is supported upon a front rail 24, which may be of the usual sort, and is also supported upon a rear rail 25, which advantageously is located considerably lower than in the ordinary Underwood standard typewriting machine, so that webs 26, drawn over a rear paper-table 27, will be guided above the rail 25 and be directed to the platen at the usual rear feed-roll 28 at the front end of a substantially horizontal stretch of web.

As herein illustrated, the web 26 may be a fan-fold web, comprising' three thicknesses for the sake of illustration, and between these are shown threaded carbon-sheets 29 which are held in any suitable manner to the clip bars 30 of a carbon-paper carriage 31, which may resemble, in many of its details, the usual Underwoodfan-fold carbon-carriage. The carriage is shown as running' upon rails 32 which form a rearward extension of the typewriter carriage, said extension being supported at its rear end by a roll 33 running upon a rail 34 forming a fixed extension 35 of the typewriter frame.

In order to guide the webs 26 to the carbon-carriage 31, they may be drawn over a rear bar 36 of the carriage provided with any usual or suitable form of edge gages (not shown). When the webs are introduced into the machine, they pass over the aforesaid paper-table 27 to the rear feedroll 28 and then are guided upwardly by an apron 37, which maybe carried on aA rod 37 a fixed to the shift-frame, so that the webs pass between the front feed-rolls 38 and the platen 5, and then up in-front of the platen past the type-guide 19 and the wing scales (not shown), and then onto a guide or directrix comprising a swing paper-table 39 above or at the delivery side of the platen. The apron 37 may extend well up toward the printing line, so that a tangent drawn from its upper edges rises at an angle of about 600. i

The swing paper-table 39 is herein shown as provided with brackets 40 at its ends, said brackets being j ournaled by hubs 41 upon the platen axle 6, to permit the swing table to l be swung forward from a stop 42, against which it normally rests, to the Fig. 3 position, at which it is arrested by the stop 42 fast upon an end plate 43 of the shift-frame.v The bracket 40 is provided with a tail 44 which arrests the swing table 39 by striking the stop pin 42 when the table reaches its proper position. When the table 39 is tion, so that it will be caughtin said swun forward to its Fig. 3 osition, the angle o arc through which t e Webs 26 and the carbons 29 between them are turned is only about 60, and it has been found that this arc on the ordinary .Underwood standard platen is sufiiciently'small to allow the carbons to slip over the webs sufficiently readily for the purpose in hand. When .the paper-table 39 is in the Fig. 3 position, the typist holds the leading ends of the webs gaged against a suitable adjustable end gage v45 fast upon an upward extension or gage bar 46 of the table 39, and then pushes the carbon-paper carriage 31 rearwardly by means of its forwardly-extending handle 47.

There may be provided an adjustablestop 47a for arresting the carriage 31 when the carbons 29 have reached any suitable point below the severing knife 48, which is fast to the table 39 and stands in front of it so that the webs and carbon-sheets are threaded between the knife and the table.

When the carbon-sheets have been brought behind the knife 48, the typist ma swing the swing table 39 rearwardly to its ig. 1 posis1- tion by means of the hook 49, which is a apted to catch over a in 50 upon the swinging bracket 4() and hold) the sw1ng table 39 in its normalposition. The webs may then be severed by drawing them against the knife, the.

ywebs usually being held sufficiently firmly by the feed-rolls 28l and 38. In order to enable the swing table 39 to be readily released from 'the hook\49, there. is provided a handle 51 forming a bell-crank extension of the hook 49 and adapted to swing ity on its' pivot 52 against the tension of a spring 53, which normally holds it in effective position. A stop 54 holds the hook 49 in position to be cammed upward lby the pin 50 when the swing table 39 is swung backward.

In order to relieve the typist of the need of separately casting off the feed-rolls 28 and 38, and to insure tlyit the parts are actuated in the right order, the swinging bracket 40 may be connected by a link 55 to a rock arm 56 fast upon the usual feed-roll castingoi' shaft 57 of the Underwood shift frame, the connections being such that when `the hook 49 holds the swing table 39 rearwardly the feed-rolls are effective, but when the swing table is in the Fig. 3 position the feedrolls are automatically released.

To facilitate the guiding of the webs l26 across the paper-table 27 to the platen, there may be provided a paper shield 58, which lies above the paper-table 27, and, like it, is supported at each end by a bracket 59 fast in the typewriter carriage frame 11. To prevent the accidental insertion of sheets above the paper shield l58, there may be provided a thin cross-plate 60 connecting the shield 58 to make sure that the typist will not accidentally slip the webs into the wrong opening.

It will be observed that the usual linespacewheel 61 of the Underwood standard typewriting machine may be fast to the platen axle, so that the usual. line-space slide 62 may turn it when driven` by the line-space handle 63. To facilitate entering the webs from the rear, both the paperimprovements may be used without others.

Having thus described my invention, I claim:
